Description

Technical Field

[0001] This invention relates to the field of lithium battery processing technology, specifically to a lithium battery drying equipment. Background Technology

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, its processing, storage, and use require very strict environmental conditions. With the development of science and technology, lithium-ion batteries have now become mainstream. Drying refers to a process of removing solvents while retaining solid content, typically involving the introduction of hot air to evaporate and remove moisture from the material. Drying is essential when lithium-ion batteries are damp. Existing lithium-ion battery drying equipment usually only allows for the drying of one battery group at a time, resulting in a slow drying rate during lithium-ion battery processing. Furthermore, the poor gas flow within the drying chamber prevents the high-temperature gas from fully contacting the lithium-ion batteries, further reducing the drying rate. Therefore, this invention provides a lithium-ion battery drying device. Summary of the Invention

[0003] The purpose of this invention is to provide a lithium battery drying device to solve the problems mentioned in the background art.

[0004] The technical solution of the present invention is: a lithium battery drying device, comprising a base plate, four sets of support rods fixedly connected in an array on the top of the base plate, a top plate fixedly connected between the tops of the four sets of support rods, a sealing base fixedly connected to the top of the base plate, nine sets of main housings fixedly connected in an array on the bottom inner side of the sealing base, auxiliary housings fixedly connected to the side walls of the main housings, a transmission assembly rotatably connected to the side walls of the auxiliary housings, a linkage assembly meshing with the transmission assembly rotatably connected between three adjacent sets of main housings, a second transmission rod rotatably connected to the bottom inner cavity of the main housing, a worm gear meshing with the linkage assembly fixedly connected to the body of the second transmission rod, and a disc fixedly connected to the top of the second transmission rod, the top of the disc being open at equal angles. The system has four sets of annular grooves. Four sets of sliding grooves are equally angled on the top of the main housing. Sliding rods are symmetrically fixed between the two end walls of each sliding groove. Clamping assemblies are slidably arranged between two sets of sliding rods, with their bottoms inserted into the annular grooves. Hydraulic push rods are symmetrically fixedly installed on the top of the top plate. A sealing cover is fixedly connected between the telescopic ends of the bottom of two sets of hydraulic push rods. An air outlet pipe is connected to one side of the top of the sealing cover. A mounting bracket is fixedly connected between the top of the sealing cover and the side wall of the air outlet pipe. A drive assembly is fixedly installed on the top of the mounting bracket. A rotating rod is damped and rotatably connected between the two end walls of the inner cavity of the air outlet pipe. A sealing plate is fixedly connected to the rotating rod. A drive assembly is fixedly connected to the side of the rotating rod outside the air outlet pipe. The components are unidirectional and work together. A circulation component, meshing with a drive component, is rotatably connected to the top of the mounting bracket and extends downwards into the inner cavity of the sealing cover. A circulation duct is located at the top of the inner cavity of the sealing cover, and the circulation component is situated within the duct. Adsorption boxes are symmetrically fixed to the side walls at both ends of the inner cavity of the sealing cover. A heating component is located at the bottom of the base plate, and an air inlet pipe connects the heating component to the sealing cover. A controller is fixedly mounted on the side wall of the base plate, and the controller is electrically connected to the hydraulic push rod, drive component, and heating component. In use, the operator places multiple sets of lithium batteries to be dried on top of the corresponding main housing, positioning the lithium batteries between four surrounding clamping components; then the operator rotates... The transmission component rotates, driving three sets of linkage components to rotate. These linkage components drive three adjacent sets of turbines to rotate, which in turn drive a second transmission rod to rotate. The second transmission rod then drives a disc to rotate. Under the action of the disc, the clamping component retracts along the annular groove on the disc towards the center of the top of the main housing, thus abutting against the side wall of the lithium battery. This completes the clamping and fixing operation of the lithium battery. This device can clamp and fix multiple sets of lithium batteries simultaneously. During subsequent drying operations, multiple sets of lithium batteries that have completed the fixing operation can also be dried simultaneously. This improves the drying efficiency in the lithium battery processing process by increasing the number of lithium batteries that can be dried in a single operation.Subsequently, the hydraulic push rod moves the sealing cover downwards, ensuring a tight fit between the bottom of the sealing cover and the top of the sealing base. Then, the heating component operates, delivering dry, high-temperature air into the sealing cover through the inlet pipe. This continuous supply of dry, high-temperature air causes the original room-temperature air inside the sealing cover to be discharged through the outlet pipe. Once the inner cavity of the sealing cover is filled with dry, high-temperature air, the heating component stops operating, and the drive component rotates forward. During this forward rotation, the one-way component engages with the output end of the drive component, causing the drive component to synchronously rotate the one-way component. The one-way component then rotates the rotating rod, which in turn rotates the sealing plate. This changes the sealing plate from a vertical to a horizontal position and closes the outlet pipe, thus sealing the cover. The drive component then reverses direction. During reversal, the unidirectional component is not engaged with the output of the drive component, allowing the drive component's output to idle within the unidirectional component. Simultaneously, the drive component rotates the circulation component. Under the action of the circulation component, airflow from both ends of the circulation duct enters the duct and exits from the bottom, accelerating gas flow within the duct. This ensures sufficient contact between the dry, high-temperature gas and the lithium battery. This device increases the drying rate of the lithium battery by accelerating gas flow, thus shortening the drying time and improving drying efficiency in the lithium battery processing. Furthermore, when moisture inside the lithium battery evaporates due to heat, the circulation component accelerates the contact rate between the moisture and the adsorbent in the adsorption box, allowing for rapid absorption and preventing moisture from re-adhering to the battery surface.

[0005] Preferably, the transmission assembly includes a transmission rod rotatably connected to the side wall of the auxiliary housing. Three sets of bevel gears are fixedly connected at equal intervals on the transmission rod. When the operator rotates the transmission rod, the transmission rod drives the three sets of bevel gears to rotate.

[0006] Preferably, the linkage assembly includes a worm gear rotatably connected to the side wall of the main housing, and a bevel gear two meshing with a bevel gear one fixedly connected to the end of the worm gear. The bevel gear one drives the bevel gear two to rotate, and the bevel gear two drives the worm gear to rotate.

[0007] Preferably, the clamping assembly includes a vertical plate slidably disposed between two sets of sliding rods. A clamping rod is slidably disposed on the side wall of the vertical plate. A clamping plate is fixedly connected to the end of the clamping rod. A spring is wound around the body of the clamping rod and is connected between the clamping plate and the vertical plate. An insert rod is fixedly connected to the bottom of the vertical plate and extends into an annular groove. Under the action of the disc, the insert rod retracts along the annular groove on the disc toward the top center of the main housing. The insert rod drives the vertical plate, the clamping rod, and the clamping plate to move toward the top center of the main housing, thereby causing the clamping plate to abut against the side wall of the lithium battery, thus completing the clamping and fixing operation of the lithium battery. In addition, the spring can reduce the rigid contact between the clamping plate and the side wall of the lithium battery to a certain extent, thereby reducing the probability of wear on the lithium battery.

[0008] Preferably, the drive assembly includes a motor fixedly mounted on the top of the mounting bracket, a transmission rod three fixedly connected to the output end of the motor, a bevel gear three fixedly connected to the body of the transmission rod three, and a drive gear fixedly connected to the end of the transmission rod three. The drive assembly drives the transmission rod three, the bevel gear three, and the drive gear to rotate.

[0009] Preferably, the circulation assembly includes a transmission rod four rotatably connected to the mounting frame, a bevel gear four fixedly connected to the top of the transmission rod four and meshing with a bevel gear three, and four sets of circulation fan blades fixedly connected to the bottom of the transmission rod four at equal angles. The bevel gear three drives the bevel gear four to rotate, the bevel gear four drives the transmission rod four to rotate, and the transmission rod four drives the four sets of circulation fan blades to rotate.

[0010] Preferably, the unidirectional component includes a mounting cylinder fixedly connected to the end of the rotating rod. Six sets of mounting platforms are fixedly connected at equal angles on the inner wall of the mounting cylinder. A baffle is fixedly connected to the side wall of the mounting platform. A stop rod is rotatably connected to the mounting platform. Six sets of springs are connected at equal angles on the inner wall of the mounting cylinder, and the springs are connected between the inner wall of the mounting cylinder and the stop rod. When the drive gear rotates forward, the drive gear engages with the stop rod. This causes the drive gear to drive the mounting cylinder to rotate synchronously forward. The mounting cylinder drives the rotating rod to rotate forward, and the rotating rod drives the sealing plate to rotate forward. This causes the sealing plate to switch from a vertical state to a horizontal state, and the vent pipe to switch from an open state to a closed state, thereby making the sealing cover in a sealed state.

[0011] Preferably, the heating assembly includes a dust collector, a drying chamber, an air pump, and a heating chamber, all fixedly installed at the bottom of the base plate. The dust collector and the drying chamber are connected by pipes, the drying chamber and the air pump are connected by pipes, and the air pump and the heating chamber are connected by pipes. When the air pump operates, external gas first enters the dust collector, where it filters out dust. Then, the gas enters the drying chamber, where a desiccant absorbs moisture. Next, the gas enters the heating chamber, where it heats the gas, turning it from room temperature to high temperature. Finally, the dried, high-temperature air is delivered to the sealed enclosure through the inlet pipe. By continuously supplying the sealed enclosure with dried, high-temperature air, the original room temperature air inside the sealed enclosure is discharged through the outlet pipe.

[0012] This invention provides an improved lithium battery drying device, which has the following improvements and advantages compared with the prior art:

[0013] Firstly, the present invention provides a lithium battery drying equipment that can simultaneously clamp and fix multiple groups of lithium batteries. During subsequent drying operations, the multiple groups of lithium batteries that have been fixed can also be dried simultaneously, thereby improving the drying efficiency in the lithium battery processing process in terms of the number of lithium batteries dried in a single operation.

[0014] Secondly, the spring in the lithium battery drying equipment described in this invention can reduce the rigid contact between the clamping plate and the side wall of the lithium battery to a certain extent, thereby reducing the probability of wear on the lithium battery.

[0015] Thirdly, the present invention provides a lithium battery drying equipment. This device accelerates the flow of gas inside the sealed cover, so that the dry high-temperature gas inside the sealed cover can fully contact the lithium battery, thereby increasing the drying rate of the lithium battery and shortening the drying time of the lithium battery. This improves the drying efficiency in the lithium battery processing process from the perspective of the drying time of a single lithium battery.

[0016] Fourthly, the lithium battery drying equipment described in this invention allows for the acceleration of the contact rate between the water vapor and the adsorbent in the adsorption box after the water inside the lithium battery evaporates due to heat. This enables the water vapor to be absorbed quickly, thereby preventing the water vapor from re-attaching to the surface of the lithium battery. Attached Figure Description

[0031] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] This invention provides an improved lithium battery drying device. The technical solution of this invention is as follows:

[0033] like Figures 1-11As shown, it includes a base plate 1, four sets of support rods 2 are fixedly connected to the top of the base plate 1 in an array, a top plate 3 is fixedly connected between the tops of the four sets of support rods 2, a sealing base 4 is fixedly connected to the top of the base plate 1, nine sets of main housings 5 ​​are fixedly connected to the bottom of the inner side of the sealing base 4, an auxiliary housing 6 is fixedly connected to the side wall of the main housing 5, a transmission assembly 7 is rotatably connected to the side wall of the auxiliary housing 6, a linkage assembly 8 that meshes with the transmission assembly 7 is rotatably connected between three adjacent sets of main housings 5, a second transmission rod 9 is rotatably connected to the bottom of the inner cavity of the main housing 5, a worm gear 10 that meshes with the linkage assembly 8 is fixedly connected to the body of the second transmission rod 9, a disc 11 is fixedly connected to the top of the second transmission rod 9, and four sets of annular grooves 12 are equally spaced on the top of the disc 11. The top of the housing 5 has four sets of sliding grooves 13 at equal angles. Sliding rods 14 are symmetrically fixedly connected between the two end sidewalls of the inner side of each sliding groove 13. A clamping assembly 15 is slidably arranged between two sets of sliding rods 14, and the bottom of the clamping assembly 15 is inserted into an annular groove 12. Hydraulic push rods 16 are symmetrically fixedly installed on the top of the top plate 3. A sealing cover 17 is fixedly connected between the bottom telescopic ends of two sets of hydraulic push rods 16. An air outlet pipe 18 is connected to one side of the top of the sealing cover 17. A mounting bracket 19 is fixedly connected between the top of the sealing cover 17 and the sidewall of the air outlet pipe 18. A drive assembly 20 is fixedly installed on the top of the mounting bracket 19. A rotating rod 21 is damped and rotatably connected between the two end sidewalls of the inner cavity of the air outlet pipe 18. A sealing plate 22 is fixedly connected to the body of the rotating rod 21. A one-way component 23, which cooperates with the drive assembly 20, is fixedly connected to one side outside the air outlet pipe 18. A circulation component 24, which meshes with the drive assembly 20, is rotatably connected to the top of the mounting bracket 19. The circulation component 24 extends downward into the inner cavity of the sealing cover 17. A circulation duct 25 is provided at the top of the inner cavity of the sealing cover 17, and the circulation component 24 is located within the circulation duct 25. Adsorption boxes 26 are symmetrically fixedly connected to the side walls at both ends of the inner cavity of the sealing cover 17. A heating component 27 is provided at the bottom of the base plate 1. An air inlet pipe 28 connects the heating component 27 and the sealing cover 17. A controller 29 is fixedly installed on the side wall of the base plate 1, and the controller 29 is electrically connected to the hydraulic push rod 16, the drive assembly 20, and the heating component 27. At this time, the staff places multiple sets of lithium batteries to be dried on the top of the corresponding main housing 5, and positions the lithium batteries between the four sets of clamping components 15 arranged around them; then the staff rotates the transmission component 7, which drives the three sets of linkage components 8 to rotate, the linkage components 8 drive the three adjacent sets of turbines to rotate, the turbines drive the transmission rod 9 to rotate, and the transmission rod 9 drives the disc 11 to rotate. Under the action of the disc 11, the clamping components 15 retract along the annular groove 12 on the disc 11 towards the top center of the main housing 5, so that the clamping components 15 abut against the side wall of the lithium battery, thereby completing the clamping and fixing operation of the lithium battery by the clamping components 15.This device can clamp and fix multiple sets of lithium batteries simultaneously. During subsequent drying operations, it can also dry multiple sets of fixed lithium batteries simultaneously, thus improving the drying efficiency in the lithium battery processing process by increasing the number of lithium batteries dried in a single operation. Then, the hydraulic push rod 16 moves the sealing cover 17 downwards, ensuring a tight fit between the bottom of the sealing cover 17 and the top of the sealing base 4. Following this, the heating component 27 operates, delivering dry, high-temperature air into the sealing cover 17 through the air inlet pipe 28. The heating component 27 continuously delivers dry, high-temperature air into the sealing cover 17. Warm air is introduced, causing the original room-temperature air inside the sealing cover 17 to be discharged through the air outlet 18. After the dry, high-temperature air fills the inner cavity of the sealing cover 17, the heating component 27 stops operating, and the driving component 20 rotates forward. When the driving component 20 rotates forward, the one-way component 23 engages with the output end of the driving component 20. This causes the driving component 20 to drive the one-way component 23 to rotate synchronously forward. The one-way component 23 drives the rotating rod 21 to rotate forward, and the rotating rod 21 drives the sealing plate 22 to rotate forward. This causes the sealing plate 22 to switch from a vertical state to a horizontal state, and... The trachea 18 switches from an open to a closed state, thus sealing the cover 17. Then, the drive assembly 20 reverses direction. When the drive assembly 20 reverses, the one-way component 23 is not engaged with the output end of the drive assembly 20, allowing the output end of the drive assembly 20 to idle within the one-way component 23. Simultaneously, the drive assembly 20 drives the circulation component 24 to rotate. Under the action of the circulation component 24, the airflow inside the cover 17 enters the circulation duct 25 from both ends and then exits from the bottom of the circulation duct 25, thereby increasing... The rapid flow of gas within the sealing cover 17 ensures sufficient contact between the dry, high-temperature gas and the lithium battery. This device increases the drying rate of the lithium battery by accelerating the gas flow within the sealing cover 17, thereby shortening the drying time. This improves the drying efficiency of the lithium battery processing by reducing the drying time of a single lithium battery cycle. Furthermore, when the moisture inside the lithium battery evaporates due to heat, the circulation component 24 accelerates the contact rate between the water vapor and the adsorbent in the adsorption box 26, allowing the water vapor to be quickly absorbed and preventing it from re-adhering to the lithium battery surface.

[0034] Furthermore, the transmission assembly 7 includes a transmission rod 71 rotatably connected to the side wall of the auxiliary housing 6. Three sets of bevel gears 72 are fixedly connected at equal intervals on the transmission rod 71. When the operator rotates the transmission rod 71, the transmission rod 71 drives the three sets of bevel gears 72 to rotate.

[0035] Furthermore, the linkage component 8 includes a worm gear 81 rotatably connected to the side wall of the main housing 5. A bevel gear 82 is fixedly connected to the end of the worm gear 81 and meshes with a bevel gear 72. The bevel gear 72 drives the bevel gear 82 to rotate, and the bevel gear 82 drives the worm gear 81 to rotate.

[0036] Furthermore, the clamping assembly 15 includes a vertical plate 151 slidably disposed between two sets of sliding rods 14. A clamping rod 152 is slidably disposed on the side wall of the vertical plate 151. A clamping plate 153 is fixedly connected to the end of the clamping rod 152. A spring 154 is wound around the body of the clamping rod 152 and is connected between the clamping plate 153 and the vertical plate 151. An insert rod 155 is fixedly connected to the bottom of the vertical plate 151 and extends into the annular groove 12. Under the action of the disc 11, the insert rod 155... 5. The disc retracts along the annular groove 12 on the disc 11 toward the top center of the main housing 5. The inserted rod 155 drives the vertical plate 151, the clamping rod 152 and the clamping plate 153 to move toward the top center of the main housing 5, thereby causing the clamping plate 153 to abut against the side wall of the lithium battery, thus completing the clamping and fixing operation of the clamping plate 153 on the lithium battery. In addition, the spring 154 can reduce the rigid contact between the clamping plate 153 and the side wall of the lithium battery to a certain extent, thereby reducing the probability of wear on the lithium battery.

[0037] Furthermore, the drive assembly 20 includes a motor 201 fixedly mounted on the top of the mounting bracket 19. A transmission rod 202 is fixedly connected to the output end of the motor 201. A bevel gear 203 is fixedly connected to the rod body of the transmission rod 202. A drive gear 204 is fixedly connected to the end of the transmission rod 202. The drive assembly 20 drives the transmission rod 202, the bevel gear 203 and the drive gear 204 to rotate.

[0038] Furthermore, the circulation assembly 24 includes a transmission rod 241 rotatably connected to the mounting bracket 19. A bevel gear 242, which meshes with a bevel gear 203, is fixedly connected to the top of the transmission rod 241. Four sets of circulation fan blades 243 are fixedly connected to the bottom of the transmission rod 241 at equal angles. The bevel gear 203 drives the bevel gear 242 to rotate, the bevel gear 242 drives the transmission rod 241 to rotate, and the transmission rod 241 drives the four sets of circulation fan blades 243 to rotate.

[0039] Furthermore, the one-way component 23 includes a mounting cylinder 231 fixedly connected to the end of the rotating rod 21. Six sets of mounting platforms 232 are fixedly connected at equal angles on the inner wall of the mounting cylinder 231. A baffle 233 is fixedly connected to the side wall of the mounting platform 232. A stop rod 234 is rotatably connected to the mounting platform 232. Six sets of springs 235 are connected at equal angles on the inner wall of the mounting cylinder 231. The springs 235 are connected between the inner wall of the mounting cylinder 231 and the stop rod 234. When the drive gear 204 rotates forward, the drive gear 204 engages with the stop rod 234. This causes the drive gear 204 to drive the mounting cylinder 231 to rotate forward synchronously. The mounting cylinder 231 drives the rotating rod 21 to rotate forward. The rotating rod 21 drives the sealing plate 22 to rotate forward. This causes the sealing plate 22 to switch from a vertical state to a horizontal state and the exhaust pipe 18 to switch from an open state to a closed state, thereby making the sealing cover 17 in a sealed state.

[0040] Furthermore, the heating assembly 27 includes a dust collection box 271, a drying box 272, an air pump 273, and a heating box 274, all fixedly installed at the bottom of the base plate 1. The dust collection box 271 and the drying box 272 are connected by a pipe, the drying box 272 and the air pump 273 are connected by a pipe, and the air pump 273 and the heating box 274 are connected by a pipe. When the air pump 273 operates, external gas first enters the dust collection box 271, where it filters out dust. Then, the gas enters the drying box 272, where the desiccant absorbs moisture from the gas. Next, the gas enters the heating box 274, where it heats the gas, turning it from room temperature to high temperature. Finally, the dried, high-temperature air is delivered to the sealing cover 17 through the air inlet pipe 28. By continuously supplying the sealed cover 17 with dried, high-temperature air, the original room temperature air inside the sealed cover 17 is discharged through the air outlet pipe 18.

[0041] Working principle: When in use, the operator places multiple sets of lithium batteries to be dried on the top of the corresponding main housing 5, so that the lithium batteries are located between the four sets of clamping components 15 arranged around them.

[0042] Subsequently, the operator rotated transmission rod 71, which in turn rotated three sets of bevel gears 72. These bevel gears 72 then rotated bevel gear 82, which in turn rotated worm gear 81. Worm gear 81 then rotated three adjacent sets of turbines, which in turn rotated transmission rod 9. Transmission rod 9 then rotated disk 11. Under the action of disk 11, the insertion rod 155 moved along the annular groove 12 on disk 11 towards the main housing. The top center of the main housing 5 contracts, and the inserted rod 155 drives the vertical plate 151, clamping rod 152 and clamping plate 153 to move towards the top center of the main housing 5, so that the clamping plate 153 abuts against the side wall of the lithium battery, thereby completing the clamping and fixing operation of the lithium battery. This device can clamp and fix multiple sets of lithium batteries at the same time. When performing the drying operation, multiple sets of lithium batteries that have completed the fixing operation can also be dried at the same time. This improves the drying efficiency in the lithium battery processing process in terms of the number of lithium batteries dried in a single operation.

[0043] In addition, the spring 154 can reduce the rigid contact between the clamp 153 and the side wall of the lithium battery to a certain extent, thereby reducing the probability of wear on the lithium battery.

[0044] Subsequently, the hydraulic push rod 16 drives the sealing cover 17 to move down, making the bottom of the sealing cover 17 fit tightly against the top of the sealing base 4. Then, the air pump 273 operates, and the external gas first enters the dust removal box 271, where the dust removal box 271 filters out the dust in the gas. Then, the gas enters the drying box 272, where the desiccant absorbs the moisture in the gas. Then, the gas enters the heating box 274, where the heating box 274 heats the gas, turning the room temperature gas into a high temperature gas. Finally, the dry, high temperature air is delivered to the sealing cover 17 through the air inlet pipe 28. By continuously delivering dry, high temperature air into the sealing cover 17, the original room temperature air inside the sealing cover 17 is discharged from the air outlet pipe 18.

[0045] After the dry, high-temperature air fills the inner cavity of the sealing cover 17, the air pump 273 stops operating. Then, the motor 201 drives the drive gear 204 to rotate forward. When the drive gear 204 rotates forward, it engages with the stop rod 234. This causes the drive gear 204 to drive the mounting cylinder 231 to rotate forward synchronously. The mounting cylinder 231 drives the rotating rod 21 to rotate forward, and the rotating rod 21 drives the sealing plate 22 to rotate forward. This causes the sealing plate 22 to switch from a vertical state to a horizontal state, and the exhaust pipe 18 to switch from an open state to a closed state, thereby making the sealing cover 17 a sealed state.

[0046] Subsequently, motor 201 drives drive gear 204 to reverse. When drive gear 204 reverses, the stop lever 234 does not engage with drive gear 204, allowing drive gear 204 to idle inside mounting cylinder 231. Simultaneously, motor 201 drives bevel gear 3 203 to rotate, bevel gear 3 203 drives bevel gear 4 242 to rotate, bevel gear 4 242 drives transmission rod 4 241 to rotate, and transmission rod 4 241 drives four sets of circulating fan blades 243 to rotate. Under the action of the annular fan blades 243, the airflow inside the sealing cover 17 enters the circulating air duct 25 from both ends and then exits from the bottom of the circulating air duct 25, thereby accelerating the flow of gas inside the sealing cover 17. This allows the dry, high-temperature gas inside the sealing cover 17 to fully contact the lithium battery. This device increases the drying rate of the lithium battery by accelerating the flow of gas inside the sealing cover 17, thereby shortening the drying time of the lithium battery. This improves the drying efficiency in the lithium battery processing process from the perspective of the drying time of a single lithium battery.

[0047] In addition, when the moisture inside the lithium battery evaporates due to heat, the circulation component 24 can accelerate the contact rate between the water vapor and the adsorbent in the adsorption box 26, thereby allowing the water vapor to be absorbed quickly and preventing the water vapor from re-attaching to the surface of the lithium battery.

[0048] The foregoing description enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
